Memphis, TN – Ultra-Gold™ ARC Series Aluminum Rocker Arms have been expanded to include LS1, LS2, LS3, LSLS Non-Adjustable Ultra-Gold ARC Series Aluminum Rocker Arms6 and LS-based truck applications.
COMP Cams® LS Non-Adjustable Ultra-Gold™ ARC Series Aluminum Rockers are more durable than both stock rockers and other aftermarket aluminum rocker designs. A CNC-extruded body provides increased strength and stiffness, which is especially important for higher-load springs. The roller tip meanwhile is an upgrade over the stock slider, which is not meant for use with high-lift cams and springs that see increased load. What’s more, a larger-than-stock billet trunnion package features captured needle bearings to help prevent failure. These pedestal-mount rocker arms are offered in 1.72 and 1.82 ratios, with the 1.82 option providing a convenient way of increasing valve lift without having to undergo a full cam swap. The rockers include pedestal mounts and bolts, and feature a non-adjustable, bolt-down design. COMP Cams® LS Non-Adjustable Ultra-Gold™ ARC Series Aluminum Rocker Arms also feature a limited lifetime warranty. Aftermarket valve covers may be required.
